You said "best college TEAM," so the answer will always be 1995 Nebraska Cornhuskers. Beat Miami in the last game at the Orange Bowl for the national title in 1994 with Warren Sapp/Ray Lewis knowing they were going to run the ball right up the middle and test them physically all night long. Also beat FSU for the title the year before but were jobbed by the refs. Then destroyed undefeated Florida who won the title in 1996 the year after. A clean-*** three year sweep of the best talent in Florida. The most dominant TEAM of all time. Not collection of individual talents, but TEAM. 11 players doing their job in unison to win the game.
And after them I got 2019 LSU with Joe Burrow growing up in Nebraska as the QB. Then Alabama.
